INHALER.

SPECIFICATION forming part of Letters Patent No. 314,485, dated March 24-, 1885.

Application filed October 14, 1884.

To all whom it may concern.-

Be it known that I, WILLIAM B. SPENoER, a citizen of the United States, residing at Terre Haute, in the county of Vigo and State of Indiana, have invented a new and useful Improvement in Pulmonic Shields, of which the following is a specification, reference being'lrad to the accompanying drawings.

My invention has relation to pulmonic shields designed to prevent catching of dis ease either in the open air or in dissectingrooms, sick-rooms, morgues, or elsewhere; and it consists in the construction and novel arrangement of parts, as will be hereinafter fully described and claimed.

In the drawings, Figure 1 is a view in perspective of my improved pulmonic shield in place upon the wearer. Fig. 2 is a view in perspective showing the shield open; and Fig. 3 is a view of a modification wherein the wiregauze screen is replaced by threads. Fig. 4 is a view in perspective of another modification wherein the hinged lid of the shield is provided with wire-gauze and the body ofthe shield is provided with threads.

Referring by letter to the accompanying drawings, A designates the body of the pulmonic shield, which may be made of any suitable material, and should be of a configuration that when in place will cover both the mouth and the nose of the wearer. This body A has ascreen, B, which may be either of finely-meshed wire-gauze B or of parallel wire thread 0, placed closely together by carrying it back and forth across the opening D in the body A, and passing the thread 0 throughperforations E in close proximity to the edge of the body A around the openingD or perforated sheet metal or other perforated material.

To the lower enlarged side of the body A is hinged a'rim, E, which conforms in outline to the outline of the body A, and fits the body A around the opening D. The rim E is pro- (No model.)

vided with a wire-gauze screen, F, which is 4 5 suitable disinfecting material when I am about k to wear the shield. \Vhen worn in the open air,the shield will prevent irritating particles or substances from entering thelungs. I may reverse the positions of the wire threads and the wire-gauze and place the threads in the hinged rim; or I may omit the screen and use the threads in both the body and the rim; or I may omit the threads and use the wire-gauze in both rim and body; or I may use perforated sheet metal or other perforated mate rial for screens instead of both wire-gauze and threads, as before mentioned, in both rim and body. I Having thus fully described my invention, what I claim as new, and desire to secure by Letters Patent of the United States, is-

A pulmonie shield comprising an approxiinatel y oval-shaped body extended forward at the upper end to receive the nose, and openwork connecting the sides of the body, in combination with a rim hinged to the body, and having its sides connected by open-work and fitting over'the sides of the body, a catch for holding the rim to the body, and bands connecting with the rim, as and for the purpose set forth.

In testimony that I claim the foregoing as my own I have hereto affixed my signature in presence of two witnesses.

WILLIAM B. SPENCER.
